The Machine Crusade (Legends of Dune #2)

by Brian Herbert

“It enables emotions to rule, rather than the logic under which we operate. Humans are inclined to take irrational actions because their religions give them the righteous high ground. To them, our conflict becomes more than a war — it is a holy undertaking of the highest order.”

Unfortunately, some wars are won by the side that is the most fanatical in a religious sense. The victorious leaders harness the holy energy of collective insanity.

Lack of opportunities did not necessarily make an individual stupid, but only shifted his intelligence to a form suited to survival rather than creativity.
